During this construction of tunnel is built; bulkhead wall operator guards diaphragm wall; its degree of depth reaches more than 50 meter deeply; and need to pass through 25m thick sand bed; joint adopts cross steel plate rigid joint, and construction quality requires high, and difficulty is large; therefore in order to ensure construction of diaphragm wall quality, need to take to prevent concrete slurry from streaming measure.
Summary of the invention
For above-mentioned prior art, the utility model provides a kind of immersed tube tunnel underground continuous wall connector with Concrete Anti by-pass means.Can prevent ultra-deep underground continuous wall cross steel plate joint concrete slurry from occurring streaming.
Because this wall operator guards is in linkage section both sides, immersed tube tunnel bank; the space enclosing structure of digging is dredged as dry-docking, immersed tube linkage section, riverbed; stable protection is played a part to bank line; anti-by-pass means of the present utility model can ensure construction of diaphragm wall quality, strengthens the resistance to overturning of bulkhead wall operator guards.
In order to solve the problems of the technologies described above, a kind of T-shaped of the utility model welds immersed tube tunnel underground continuous wall connector entirely, the cross steel plate joint that steel plate a4 and steel plate b3 is welded into, the main muscle 2 of diaphragm wall and diaphragm wall level frame stud 1 place are provided with a cornerite reinforcing bar 5 respectively, two cornerite reinforcing bars are two concave character type reinforcing bars be arranged in juxtaposition, described steel plate a4 is arranged in the crack of two cornerite reinforcing bars 5, the two ends of described steel plate b3 are bending and weld with the outside of two cornerite reinforcing bars 5, the full welding point of T-shaped is welded with between the both sides of described steel plate b3 and the outline of diaphragm wall.
The full welding point of T-shaped comprises fixation steel plate 6, choked flow bent plate 7, stops steel plate 8; Described fixation steel plate 6 is parallel with the outline of diaphragm wall, and fixation steel plate 6 vertically inserts in steel plate b3 and 1/3rd places of fixation steel plate 6 and welds with one end of steel plate b3; One end and the fixation steel plate 6 of described choked flow bent plate 7 are fixed, and the foundation trench Tu Bi side of choked flow bent plate 7 remainder and diaphragm wall is closely connected, and described choked flow bent plate 7 surrounds filling concrete region, joint just; Stop that steel plate 8 is perpendicular to fixation steel plate 6 and one side of closely connected steel plate b3, stopping that steel plate 8 and fixation steel plate 6 are by being welded to connect, stopping that steel plate 8 is also fixing by being welded to connect with the closely connected place of steel plate b3.
Compared with prior art, the beneficial effects of the utility model are:
By adopting joint Concrete Anti by-pass means, effectively decrease diaphragm wall the streaming of slurries in filling concrete process, reduce next groove section trenching construction difficulty and risk, ensure that wall quality and resistance to overturning, thus ensure construction safety.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in further detail.
As described in Figure 1, a kind of T-shaped welds immersed tube tunnel underground continuous wall connector entirely, the cross steel plate joint that steel plate a4 and steel plate b3 is welded into, the main muscle 2 of diaphragm wall and diaphragm wall level frame stud 1 place are provided with a cornerite reinforcing bar 5 respectively, two cornerite reinforcing bars are two concave character type reinforcing bars be arranged in juxtaposition, described steel plate a4 is arranged in the crack of two cornerite reinforcing bars 5, the two ends of described steel plate b3 are bending and weld with the outside of two cornerite reinforcing bars 5, are welded with the full welding point of T-shaped between the both sides of described steel plate b3 and the outline of diaphragm wall.
The full welding point of T-shaped comprises fixation steel plate 6, choked flow bent plate 7, stops steel plate 8; Described fixation steel plate 6 is parallel with the outline of diaphragm wall, and fixation steel plate 6 vertically inserts in steel plate b3 and 1/3rd places of fixation steel plate 6 and welds with one end of steel plate b3; One end and the fixation steel plate 6 of described choked flow bent plate 7 are fixed, and the foundation trench Tu Bi side of choked flow bent plate 7 remainder and diaphragm wall is closely connected, and described choked flow bent plate 7 surrounds filling concrete region, joint just; Stop that steel plate 8 is perpendicular to fixation steel plate 6 and one side of closely connected steel plate b3, stopping that steel plate 8 and fixation steel plate 6 are by being welded to connect, stopping that steel plate 8 is also fixing by being welded to connect with the closely connected place of steel plate b3.
Embodiment
Diaphragm wall is lattice form, the degree of depth is 52.5m the most deeply, and pass through the construction of 25m thick sand bed, underground continuous wall connector adopts rigid joint cross steel plate, for the Plate Welding being respectively 20mm and 10mm by two pieces of thickness forms, middle 120mm carries out the hole of 100mm × 120mm, to ensure that concrete passes cross steel plate, is formed closely connected.Stream to prevent concrete slurry, the full welding point of T-shaped is provided with between cross steel plate and cell wall, the choked flow bent plate 7 thick by 1mm, the stop steel plate 8 that 6mm is thick, the fixation steel plate 6 that 6mm is thick, the full welding point of this T-shaped is adopted at underground continuous wall connector place, can effectively prevent in concreting process choked flow bent plate 7, stop steel plate 8, the axial impact of fixation steel plate 6, by stopping that steel plate 8 is also fixing by being welded to connect with the closely connected place of steel plate b3, greatly can strengthen the stability of the full welding point of T-shaped, the bent plate of choked flow simultaneously 7, stop steel plate 8, the seal joint structure that fixation steel plate 6 and diaphragm wall form can effectively prevent streaming of concrete slurry.
Diaphragm wall fabrication of reinforcing cage, wherein cornerite reinforcing bar 5 and the steel plate a4 in cross steel plate joint, adopt overlap joint full weld, makes the steel plate a4 of cross steel plate joint connect in aggregates with the reinforcing cage having diaphragm wall reinforcing bar and underground distribution reinforcement to form.
When diaphragm wall filling concrete, because concrete tension force causes iron sheet to be close to foundation trench Tu Bi, described choked flow bent plate 7 surrounds the region of joint filling concrete just, thus reaches prevention concrete slurry detour flow.
